[Lyle O]

I used Joe Gibbs 30 wt Break-in oil for first few hundred, then Mobil 1 10W-50 for the duration of break-in and for there-after. I didn't baby it at all, just always varied the the revs and loads, etc. Rings set beautifully. Motor runs great (5000 or so on it now); burns almost no oil, and my oil analysis shows all elements within normal range. My $.02.
